Generally, when we rent foreign servers, we recommend users to choose CN2 GIA line, because CN2 GIA direct connection line can greatly improve the access speed of the website. In addition, there are servers with bgp line, so let’s take a look at foreign servers. In addition to the cn2 line, how about the server performance of the BGP line. Let's take the US BGP server as an example to find out whether the US BGP server is worth renting.

What is the US BGP server?

BGP refers to the fact that the computer room is connected to two or more lines (multi-line interconnection), and the BGP routing protocol controls the propagation of the route and the route selection path. This kind of computer room is called a BGP computer room, and the server is Known as a BGP server.

The US BGP server has many operator lines connected to the US computer room, so in addition to China Telecom, China Mobile, and China Unicom, there are many operator lines in other countries, but they are also directly connected to the country, so it is also called the US server by many people. even. For example, BGP lines in the United States are generally counted in the bandwidth of international lines. After all, the lines in the BGP computer room only include the lines of domestic operators, as well as the networks of operators in other countries.

How is the performance of the US BGP server?

It is the international line bandwidth we often talk about. We all know that if the foreign server chooses an international line, the access speed for domestic users will not be very good. This is certain, but here are several situations:

One is that the computer room is not connected to the lines of Chinese operators, which is particularly slow for domestic users.

The second is to access the traditional Chinese operator 163 network, which is also very slow. After all, the line has not been specially optimized, plus the distance and third-party BGP.

Then there is the BGP computer room with CN2 GIA line, China Telecom, China Mobile, and China Unicom network lines optimized by CN2 line. This is the fastest line for domestic access to foreign servers. The general speed delay is around 120ms-180ms, and 120ms is the fastest Ideal speed, the current choice is CN2+BGP US server.

BGP generally refers to all lines (the American BGP server called most of the time refers to international lines), including international lines and CN2 lines, while the international bandwidth of American servers includes traditional Chinese operator network lines, but not Contains CN2.

The CN2 line bandwidth can also use the network lines of Chinese operators, that is to say, the traditional China Telecom, China Mobile, and Unicom operator networks are equivalent to sharing, while the optimized three-network direct connection means that there is no third-party BGP, which is the real meaning on the direct network. This is why the same US server has different speeds.

The US BGP server refers to the BGP multi-line server in the US computer room. Both the international network line and the CN2 network line are dispatched by the BGP routing protocol. For domestic users, the CN2 US server is recommended.
